The Keysight 11793A is a microwave converter that downconverts signals above 1.3 GHz to intermediate frequencies compatible with the 8902A measuring receiver. Signals below 1.3 GHz bypass the converter and route directly to the receiver input. For frequencies above 1.3 GHz, an internal mixer combines the input signal with an external local oscillator, producing a filtered and amplified IF output in the 10 to 700 MHz range.
Technical Specifications
• Input Signal Range: Below 1.3 GHz (direct passthrough); above 1.3 GHz (mixed with external LO)
• Output IF Range: 10 MHz to 700 MHz (typical)
• Local Oscillator Requirement: +8 dBm leveled output (nominal)
• LO Amplitude Range:
– +8 dBm to +13 dBm from 2 GHz to 18 GHz
– +7 dBm to +13 dBm from 18 GHz to 26.5 GHz (with optional amplifier)
– +0 dBm to +5 dBm from 18 GHz to 26.5 GHz (optional amplifier, lower power range)
• Power Requirements: 100, 120, 220, or 240 VAC (±5%, −10%), 48–66 Hz, 1300 VA maximum
• Physical: 4 × 17 × 22 inches; 122.3 kg net weight
– Key Features
• Dual-path signal routing optimizes dynamic range across frequency bands
• Selectable LO input connectors via front panel, front-right, or rear panel options
• Optional 18–26.5 GHz amplifier (11793A-001) boosts LO drive for extended frequency coverage
• Operates as system component with 8902A receiver and 11792A sensor module
– Typical Applications
RF signal characterization including power, AM, FM, and phase modulation measurements up to 26.5 GHz.
